Specification of Letters Patent.

Patented Nov. id, 1909.

Application filed July 11, 1906. Serial No.-325,621.

To all whom it may concern:

Be it known that L CHRISTOPHER C. Roe- BINS, citizen of the UnitedStates, and resident of Portland, in the county of Multnomah and Stateof Uregon, have invented certain new and useful Improvements inType-VVriting Machines, of which the following is a specification.

My invention relates more especially to scales for typewriting machinesand has for its main object to provide an improved scale device orheading holder having a plurality of scales, headings or indexesvariously marked for difierent kinds of work, which device may bemanipulated to bring readily any desired scale, heading or index toworking position.-

To the above and other ends the invention consists in the features ofconstruction, combinations of devices and arrangements of partshereinafter described and particularly pointed out in the claims.

In carrying out my invention in the present instance, I employ ascale-bar, headingholder or index-member which is preferably cylindricaland is provided with a number of difierent scales or headings arrangedlongitudinally of the scale bar and parallel with each other. Associatedwith the scalebar or heading-holder. is a shield, casing or housinghaving a longitudinal reading-opening or slit and within which the scalebar is adapted to be turned to bring any desired scale or headingopposite the reading-opening through which said scale or heading may beread, the other scales or headings being at the same time covered. Iprefer, as shown in the present instance, to mount the casing andscalebar on the carriage or traveling element of a typewriting machineand to make use of my improved device in connection with the usualcarriage scale and pointer of the machine. It will be apparent, however,that my novel device may be mounted on a stationary part if desired andthat the usual carriage scale may be dispensed with.

The invention is illustrated as applied to a No. 6 Remington typewritingmachine but it is to be understood that the nature of the invention issuch that it may be readily adapted to other forms of Writing machines.In the accompanying drawings, Figure l is a full-sized front to rearsectional view of the upper part of a typewriting machine embodying myinvention, parts of the machlne being omitted and parts being brokenaway. Fig. 2 is a front elevation of the parts shown in Fig. 1 but drawnto a smaller scale. Fig. 3 is an enlarged transverse sectional view ofthe casing or cover of my improved scale-bar or heading-holder, part ofone of the supporting brackets of said casing being shown associatedtherewith. Fig. 4c is a full-sized top view partly-in section of myimproved scale device, its supporting brackets and the front part of thecarriage to which said supporting brackets are secured. Fig. 5 is afull-sized detached plan view of my improved scale bar or headingholder.

In the drawings the main frame of the machine is shown as comprisingcorner posts 1 which support a top plate 2, rising from which arestandards 3 to which is fixed a cylindrical track-way 4:- Cooperatingwith the track-way are rollers 5 mounted in a carriage truck 6, saidcarriage truck being pivotally connected by a rock shaft 7 and arms 8with a rectangular platen frame comprising a rear bar 9, side bars 10and a front bar 11. A yoke piece 12, suitably secured to the front bar11, carries a wheel or roller 13 which coiiperates with a shiftablefront rail 14 secured to arms 15 pivoted on the machine frame. A rotaryplaten 16 has an axle 17 journaled in the side bars 10 of the platenframe or carrier, said carrier with the carriage truck 6 constituting aplaten carriage. A pointer 18 of suitable construction is secured to thefront rail 14 and cooperates with the usual platen scale 19, said scalebeing fastened by headed screws 20 to angled arms 21 projectingforwardly and downwardly from the under side of the front bar 11 towhich said arms are secured by headed screws 22. The carriage. feedingmechanism and printing devices may be of the usual or suitableconstruction and a description of them is not deemed necessary to acomplete understanding of the present invention.

The novel scale-bar or heading-holder is shown detached in'Fig. 5 and isdesignated as a whole by the reference numeral 23. The

body 24 of the scale bar is preferably cylin drical and if made solidshould be'ofsome comparatively light material, that shown in thedrawings being made of wood. The left end of the scale bar is preferablyreduced as indicated at 25 (Fig. 4.) and receives a" hollow corrugatedmetal handle or finger piece 26 which may be driven in place on the endof the scale-bar or otherwise suitably secured. The body portion of thebar may be formed with a plurality of scales or headings extendinglongitudinally of the scale bar and parallel with each other. In thepresent instance, however, I have preferred to mark or form such scalesor headings on a scale sheet or heading strip 27 of paper or othersuitable material, said scale sheet after being marked being rolledaround and secured to the body of the scale bar by any suitable means,such as glue, paste or the like. In the present instance the scale sheet27 is provided with a plurality or setof scales differently marked andsuch as may be used in the business of an iron and steel concern. Itwill, of course, be understood that the character and arrangement of thescales or markings on the scale sheet will difier with the character andexigencies of the business in which the scales are to be employed.

It will be apparent that with a scale bar of the dimensions shown andwith scales or headings of a width shown in Fig. 5 a considerable numberof scales may be arranged on the scale bar; six or eight, or even more,if the width of the scales be narrowed. In Fig. 5 the shading is omittedfrom the scale sheet for the sake of clearness and in Fig. 4: the scalesheet is shaded but the scales or markings are omitted from said scalesheet.

The scale-bar with the'scale sheet thereon is preferably arranged in acylindrical housmg or casing 28 preferably made of thin metal and closedat one end as by a block 29 (Fig. i) and open at the other end toreceive the scale-bar. The casing is provided at its front side with alongitudinal slit or opening 30 which is of such width that one only ofthe scales on the scale bar may be read at a time therethrough and is ofa length that corresponds substantially to the length of the carriagescale 19. The casing, it will be noted, is in the nature of a shieldwhich covers or conceals from the view of the operator the parts of thescale-bar not in use. lhe scale-bar is frictionally held in the casingso that it will remain in any position to which it may be turned, at thewill of the operator. The casing 28 is mounted in supports or brackets31 which have angularly disposed rear portions 32 formed with openingsthrough which the headed screws 20 pass, the supports being therebyclamped or secured between the heads of the screws 20 and the face ofthe carriage scale 19. The forward ends of the supports or brackets 31are curved as indicated at 33 to embrace the casing 28 near its ends,the free ends 34 of the supports 31 being-bent parallel with the bodyportions thereof and being connected with said bodv portions by sconesrivets 35. It will be noted that the forward ends of the supports 31 arein the nature of split collars which surround the casing 28 andareadapted to securely clamp said casing when the rivets are secured inplace. The parts are so proportioned and arranged that the casing 28isdisposed well forward of the carriage scale 19 and the coiiperatingpointer 18 so that the reading of said scale I and pointer 1s notinterfered with. Furthermore the reading-opening 30 in the casing isshown so disposed with relation to the scale 19 andpointer 18, that thescales on the scale bar may be in turn read through said opening inconnection with the reading of the carriage scale 19 and the pointer 18.This arrangement is a convenient one since by it I am enabled todispense withan additional pointer and scale to be used in connectionwith the scale bar; although, of

course, if desired such a pointer and such a scale may be appliedreadily to the parts shown.

Each of the scales or headings on the scale sheet or the heading strip27 is divided as usual into a number of columns, each column beingappropriately marked. When it is desired to prepare a bill or statement,

the scale-bar is turned in the casing until the scale or heading on saidscale-bar corresponding with the heading on the bill or statement to bewritten is oppositethe. reading-opening 30 in the casin and may be readtherethrough. It will be understood that the columns as marked off onthe scale or heading which is in working position will bear a particularrelation with the graduations on the regular carriage scale 19. It

will further be understood that the bill sheet, statement or work sheetto be written upon should be entered or fed into the ma chine in such away that the heading on said 'bill should bear a relation with the usualplaten scale (not shown) corresponding to the relation between theheading on the scale'bar and the carriage scale 19. It is not thoughtnecessary to describe in detail the manner tr using the scale-bar in theoperation of printing the various kinds of work sheets. Such a scale-baras the one I have shown and others having corresponding functions, aremuch used In tabular work,

and, as is well understood, tabulating devices are commonly employed tofacilitate the execution of such work. When such tabulating devices areso employed and my invention is made use of in connection therewith,said invention greatly facilitates the execution of the work as theoperator is enabled, without raisin the carriage to see just what placeor co umnar field the types will strike when actuated. The invention,however, may, of course, be employed either with or without tabulatinmechanism, and

in some instances the emp oyment of my de- 13c vice may enable theoperator to dispense with a tabulatorand attain the desired ends with asgreat or greater facility than when a tabulator is employed.

My novel device is superior to scale or heading devices heretofore knownand escially so in business in which a variety of illing or statementwork is used, since by the employment of my invention .a ccnsiderablenumber of different styles of headings or scales are readily available,it being only necessary to turn the handle 26 of the scale bar to bringone or another of such headings or scales tofworking position. As hasbeen stated the scale-bar 1s frictionally held within the casing in anydesired position, it being in the nature of a rotary core; but it will,of course, be evident that a positive retaining means ,ma be employedfor holding said scale-bar if desired. It will furthermore be a parentthat scales or headings may be ad ed or changed with facility from timeto time as the necessities of the business may require.

Various changes may be made in the details of construction andarrangements of parts without departing from the scope of my invention.

What I claim as new and desire to secure by Letters Patent, is

1. In a typewriting machine, the combination of a scale casing, aremovable core therein, and a sheath of paper or the likesuitablyattached to said core and provided with a plurality of scales.

2. In a typewriting machine, the combination of a scale casing having areading opening, a removable rotary core in said casing, and a scalesheet suitably attached to sald core and provided with a plurality ofscales.
